製品紹介
The Bently Nevada 3500/72M 176449-08 is a highly specialized Recip Rod Position Monitor designed to measure both rod drop and rod position in reciprocating compressors. As part / the Bently Nevada 3500 Machinery Protection System, this module plays a vital role in monitoring the condition / internal reciprocating compressor components, such as piston rods, crossheads, and cylinders, to detect mechanical wear or misalignment before catastrophic failure occurs.
Equipped with dual-channel inputs, the 3500/72M captures dynamic changes in rod movement using proximity probes. It integrates directly into the 3500 rack, providing continuous online surveillance and supporting automated alarms and shutdowns in response to abnormal equipment behavior. This version (176449-08) features enhanced firmware, higher resolution processing, and improved EMI tolerance—making it ideal for harsh environments in the oil, gas, and petrochemical industries.
